Solution-phase synthesis of the chalcogenide perovskite barium zirconium sulfide as colloidal nanomaterials.

Chalcogenide perovskites such as BaZrS have promising optoelectronic properties. Methods to produce these materials at low temperatures, especially in the solution phase, are currently scarce. We describe a solution-phase synthesis of colloidal nanoparticles of BaZrS using reactive metal amide precursors.
